Python次方使用方法，求兩點座標距離d

 #求兩點座標距離d

x1=eval(input())

y1=eval(input())

x2=eval(input())

y2=eval(input())

print("(",x1,",",y1,")")

print("(",x2,",",y2,")")

#方式1

import math

d=math.pow(math.pow((x1-x2),2)+math.pow((y1-y2),2),0.5)

print("Distance = %.4f" % d)

#方式2

d=(x1-x2)**2+(y1-y2)**2

d=d**0.5

print("Distance = %.4f" % d)

#方式3

d=(x1-x2)*(x1-x2)+(y1-y2)*(y1-y2)

d=math.sqrt(d)

print("Distance = %.4f" % d)
